[DSP-10] 10 mhz reference..

[Roger Hayward]

John:

The Brooks Shera frequency standard controller is meant to
frequency-correct a less-than-perfectly-stable reference....of which
most of us possess to one extent or another.  Your Rubidium standard
most-likey does not have any ability to correct its frequency (because
there will be absolutely no need!)

Good luck on the score.  It might be interesting to set up the system to
merely compare your reference against the GPS system, but I would
speculate you will be accurate-enough for applications of this sort.

I know a few of you are using the Brooks Shera Frequency standard 
controller board with an hp 10544 or 10811a  oscillator and I am 
gathering parts to build one as well but with one slight change.  On a 
whim while in California this summer I picked up an Efratom Rubidium 10 
MHz frequency standard ($200!).  I don't have a manual or anything yet 
however I know that it works.  My thought was to somehow using the 
Brooks Shera board to lock it to the gps 1pps.

Any thoughts as to how/if this might work?

Thanks

John Scherer
